Filed: 1986-03-07
Abstract: PURPOSE:To improve the rain drop resistance by generating a pressure signal in accordance with the pressure of the inside of a cylindrical member provided in parallel to the flow of a fluid, and deriving the flow velocity from this pressure signal. CONSTITUTION:A wind flows in parallel roughly along passage plates 17, 18, in a passage 20 formed by the plates 17, 18, and flows at the highest speed in the vicinity of the opening end 22a of a wind velocity detecting cylinder 22, therefore, negative pressure is generated in the cylinder 22. This negative pressure has a characteristic by which it becomes high as the wind velocity rises. Therefore, the pressure generated in the cylinder 22 is led to a semiconductor pressure sensor 24 by a pressure port 22b and a pressure leading-out tube 23, and measured, and from this pressure signal, the wind velocity is measured. Also, in case of a windy state, the negative pressure is generated in the cylinder 22, and the opening end 22a opens downward, therefore, it does not occur that a rain drop, dust, etc., invade the pressure port 22b and the pressure leading-out tube 23.

Title: Parallel analog/digital converter
Inventor: SADAMATSU HIDEAKI
IPC: H03M1/36
Filed: 1983-03-25
Abstract: PURPOSE:To reduce the nonlinear error by setting a signal wiring which applies the analog signal to a comparator in parallel and close to a series resistor which gives the reference potential to the comparator and having the same current direction between the resistor and the wiring. CONSTITUTION:The signal wiring led to comparators C1-C1024 is set in parallel and close to a series reference bias resistor Rs which applies the reference voltage to these comparators C1-C1024. At the same time, the signal input terminals AIN are set close to bias points VRH and VRL of the registor Rs as well as a corrected bias point and its opposite side. As a result, the same direction is secured between a current ib flowing to the resistor Rs and a current i'b flowing to the signal wiring. In addition, the voltage drop due to the current flowing into the comparator is set equal to those due to the resistor Rs and the resistance Ri of the signal wiring. Thus the effect of a minute current flowing into the input of comparator is eliminated, and therefore the nonlinear error can be reduced.

Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a focal shutter capable of detecting both of the abnormal operations of front and following sector groups with one detecting means. SOLUTION: When attracting force by an electromagnet for a front sector is improper, only a front sector driving member 2 is immediately turned clockwise following the returning operation of a setting member to an initial position, to obtain the contact of contact pieces 10 and 11. When the attracting force by an electromagnet for a following sector is improper, a following sector driving member 3 is immediately turned clockwise, to abut a driving pin 3c on the abutted part 13a of an arm 13. At this time, force exerted for clockwise turning the front sector driving member 2 is the force of driving springs 4 and 5. Further, the force of the driving spring 5 works many times great as dynamic output, so that the force defeats the attracting force of the front sector driving member 2, to turn it clockwise and obtain the contact between the contact pieces 10 and 11.

Title: Composite antenna
Inventor: TAKAHASHI AKIRA
IPC: H01Q9/34
Filed: 1988-03-07
Abstract: PURPOSE:To set an effective antenna length to be long, and simultaneously, to cause a construction cost to be inexpensive by fitting a bar made of fiber reinforced plastics to contain a metal conductor to the upper part of a metallic antenna and connecting the metal conductor and metallic antenna. CONSTITUTION:An antenna 12 main body is supported by an insulator 13 to a base bury-fixed on a ground, a bar 15 of the fiber reinforced plastics(FRP) to contain the metal conductor is firmly fitted to the upper part of the antenna 12 main body by a fitting 16, and the metal conductor edge of the FRP bar 15 is connected to the antenna 12. For the FRP bar 15, since an elasticity is large, a wind pressure applied at the time of a strong wind is negated by the elasticity, the wind pressure applied to the antenna 12 main body can be reduced, and the antenna 12 main body can be composed with a small rigidity in comparison with a rigid body. Thus, since an antenna height can be made large and the real number part of an antenna input impedance can be made large, a current to flow to the ground can be made small, and an antenna efficiency can be made sufficiently high.

Filed: 1982-03-30
Abstract: PURPOSE:To obtain a good weld zone which is free from a welding defect such as undercut by applying the dynamic pressure of gas to the metal melted by a heat source of high output density from the rear part thereby welding the same. CONSTITUTION:In the stage of butt welding of materials 2, 3 to be welded by a heat source of high output density such as a laser beam, a gas nozzle 8 communicating with a gas supply source 9 is positioned right behind the source 1 in the advance direction of the welding so as to follow up said source and an inert gas or active gas alone or a mixture thereof is flowed out from the nozzle.

Abstract: PURPOSE:To improve the conversion efficiencies of electromechanical energy conversion elements fixed to a resonator by forming a pair of slopes on the surface of the resonator having an almost rectangular parallelepiped body. CONSTITUTION:A resonator 2 has a rectangular projecting section 2a which is integrally protruded from the upper end face of the resonator, with the side faces of the section being perpendicular to the upper end face, at the central part of the upper end face and two slopes 2b formed by cutting off two corners of the resonator 2 on the lower end face side. Electromechanical energy conversion elements are mounted on the upper end face of the resonator 2 on both sides of the projecting section 2a. Since the slopes 3b are symmetrically provided on the opposite side of the upper end face on which the conversion elements are fixed so that the cross-sectional area of the resonator 2 in the direction parallel to the moving direction of a member to be driven can gradually decrease as going toward the lower end face of the resonator 2, the amplitude of flexural vibrations can be increased by the reflection of longitudinal vibrations and, therefore, the thrust of an ultrasonic actuator is increased.
